ADVERTISING-CLOCK.

Specification of Letters Patent.

Patented March .2, 1909.

Application filed march 11, 1908. Serial No. H0360.

I To all whom it may concern:

Be it known that 1, JOHN B. BARNETT, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Advertisirig-Clocks, of which the following a spe ification.

My invention relates to advertising devices and more is actuate at regular intervals by a time mechanism; and the object is to provide novel and useful devices for displaying advertising sheets at regular intervals and to give signals at the moment when a change of display is to be made.

Other objects and advantages will be fully explained in the following descri tion and the invention will be more particu arly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application and specification.

Figure 1 is a front elevation of advertising device, illustrating my invention. Fig. 2 is arear elevation of the operatin mechanism. Figs. 3 and 4 are broken detai views, illustinting the manner ofsus ending the advertising sheets. Figs. 5 an 6 aredetail views of the manner of carrying the sheet suspending'devices. the casing for the invention, showing a diagrammatic View of the operating mechanisrn. 8 is a detail view of the mechanism for actuating the main drive wheel. Fig. 9 is a broken edge View of the Wheel which is to be driven.

' Similar characters of reference are used to indicate the some parts throughout the several views.

A cabinet is used to carryout the objects of this invention, such as'fis shown in Fig. 1. A clock 1 of ordinary construction is mounted in the upper part of the cabinet. The clock .is used to make and break an electric circuit hereinafter described. The clock is provided with a seconds hand -2 which ismounted on: an arbor 3a One or more arms 4 maybe mounted on and carried by the arbor 3. If there are two arms 4, diagonally opposite'each other the arms 4 will strike a contactin the path ofthese arms every thirty seconds. A brush contact is yarticularly to mehhanisin which Fig. 7 is a vertical section of.

mounted in the. path-of the arms 4. The brush contact 5 is insulated from the Works of the clock and electrically connected with the cell 25 by a wire 28 which forms a part of the electric circuit hereinafter described. The arms 4 strike the contact 5 in their onnular beat and an electric circuit is made and broken every time the arms 2 touch the contact 5. v

The advertising sheets 6 are carried on rods? and the rods 7 are carriediby two sprocket chains 8 and i). The chains 3 and Q are driven by sprocket wheels 10 and ii. Idle. sprocket wheels 12 of sufiicient weight are mounted in the bight ol' the sprocket chains and 9 and serve to hold said chains and the rods 7 in operative relation. The sprocket Wheels 12 are mounted on a shaft 13 which holds these Wheels in their places as the sprocket chains move. The sprocket wheel 10 is driven by a pivoted driving dog 14 which is carried by a lever 15. The dog 14 engages pins 16 which are rigid with the wheel i0. A pivoted stop dog l7 engages the pins 16 to prevent backward turning of the sprocket wheels. The dog 17 pivotally mounted on a bracket 18 which may be .attached to the casing of the cabinet. The shaft 19 is journaled in brackets 28 which are attached to the interior of the cabinet. The dog l4 is actuated by a lever and magnets. Magnets 21 and 22 are mounted the easing or within the cabinet. The magnetsnre electrically connected by a btl 23. "The magnet 21 is electrically connected by a wire 24 with the works of the clock 1. (Tells 25 and 26 and 27 are placed in the lower part of the cabinet. The contact 5 is electrically connected to the cell .25 by a wire 28. The magnet'QQ, is electrically connected to the cell 27 by a wire 29. The cell 26 is electric allyconnected to the ccll'25 and to the cell 27 The. circuit is completed every tinae an arm-itouches the contact 5,'the.ar1ns'4 being electrically connected with the wire 24- through the works of the clock. An armsture 30 is attached to the upper arnLof the lever 15. The lever 15 is fu'lcrumed on a bracket 31 'w-l'iich may be attached to the interior of the cabinet. Every time the circuit is completedns heretofore described the armature 30 is drawn to the nicgnets and 22. This. action serves to draw the dog 14 back off of a pin 16, retracting the dog one pin. As soon as the circuit is broken, the spring 32 draws the lever 15 back to its normal position. This action causes the dog 14 to move the sprocket wheels by driving the pin 16 in front of the dog. These operations serve to revolve the wheels 1 am] 1 l as long as the clock is running.

The sheets 6 fall over the rods toward the front as the sprocket wheels'turn. A sheet may he made to fall as often as desired. number of sheets may be increased by increasing the number of the rods 7-. 4 The number of sheets to fall in a minute may he increased by increasing the number of arms 4 on the seconds arbor 3, the icompleting the circuit oftencr' The cabinet is provided with a door 35 for access to the lower part of the cabinet. The cabinet is also provided with a glass or transparent 'door 36 so that.

the advertising sheets may be seen from positions in front of the cabinet. Advertising matter is to be printed on the sheets so it can be read when the sheets fall over in front.

The advertising matter is generally printed onv that face of a sheet v'vhich is toward the door when the sheet is in a hanging position so that the advertising matter can be seen only after the sheet is released from the arms 34 and falls down in the hanging position. The sheets 6 are held in place on the rods 7 by rubber collars 33, to prevent lateral displace ment of the sheets. The collars 33 are made of rubber so that they r can be easily adj usted and being elastic, the collars will yield enough to receive the rods and will not slide on the rods unless forced and being soft, they will not mutilate the advertising sheets. In order to prevent the sheets 6 from falling over in front irregularly, each sheet is held by two arms 34, as shown in Fig. 7, until the edge of the sheet passes from under the arms 34. The sheets are thus made to fall at regular intervals. It is apparent that within the scope of the appended claims variations in the assembling of the various parts of the clock and the mechanism actuated thereby may be varied without departing from this invention. The rods 7 are loosely and removably mounted in socketscarried by the sprocket chains 8 and 9 so that the advertising sheets may be changed as often as desirable. The rods 7-are loosely mounted in the sockets on the chainsso that the rods can be removed for the purpose of placing the advertising sheets on the rods.
